eccentricityn.

/ɛksɛnˈtrɪsɪti/

Etymology: < eccentric adj. + -ity suffix.

The state or quality of being eccentric adj.

1. The quality of being abnormally centred; of not being concentric; of not having the axis in the centre. †Orig. of planetary orbits: The fact of having the earth at a distance from the centre (Obsolete exc. Historical). In modern astronomy of a circle or arc in the celestial sphere: The fact of not being concentric with the sphere.

b. as a measurable quantity.The eccentricity of an ellipse was formerly defined as the distance between the centre and one of the foci; it is now represented as an abstract number, e.g. as the ratio of the focal distance of the centre to the semi-major-axis. The more modern expression, however, for the eccentricity of all conic sections is the ratio of the focal distance (of any point in the curve) to the distance from the directrix. In the case of the ellipse this is numerically identical with the ratio previously mentioned.
